Error in web application using jxls

Question

I am using Jdeveloper 11.1.2.0 and when I use to fill a jxls excel files, I get the following error:
<Digester> <startElement> Begin event threw exception

Obviously needed are the added jar, I think the problem is the XML parser that uses Oracle Weblogic.
I did a Test Case jsf libraries leaving only 2.0, 1.2 and jars jslt to jxls and error is the same, do not pass this in a tomcat.
Any idea?

I even put the libraries in the WEB-INF/lib and the error remains the
same.
The packaged libraries are not found by the WebLogic server runtime.
Add the jxls JAR file(s) to the +\\user_projects\domains\base_domain\bin\startWebLogic+ script's
CLASSPATH variable and restart WebLogic server.
